研究表明,AMPK至少可以通过两条相互平行的途径来抑制mTORC1:其一是通过磷酸化TSC2以直接抑制RHEB和mTORC1的活力;其二是通过直接磷酸化mTORC1复合体上的RAPTOR,造成复合体结构上的变化从而抑制该复合体的活力。 这种进化上的“双保险”很可能确保了mTORC1可以在营养物质或者能量水平下降之时被有效地抑制(图4)。 尽管它们是激活的条件恰好是相反的,AMPK和mTORC1这两种激酶复合体却能使用相同的分子v-ATPase和Ragulator,在溶酶体 …

AMPK and mTOR: The Connection for Metabolic Regulation
2025年3月18日 · Additionally, AMPK directly phosphorylates Raptor, a component of mTORC1, further inhibiting its activity. A 2021 study in The Journal of Clinical Investigation highlighted how fluctuations in AMPK-mTOR signaling influence metabolic disorders, showing that impaired AMPK activation leads to unchecked mTOR activity, exacerbating insulin resistance.
